How not to write to your legislator

I'm hearing a lot about the proposed groundwater quality exemption for mining. One note caught my attention and should be pointed out as being counterproductive. This concerned citizen wrote:

"You work for citizens, Not industry! Do your job- Protect our health, lands, waters & wildlife from toxins!"

Oddly enough, this person is writing from Oklahoma, where perhaps such discourse is considered effective. And even though I don't take it personally, such a tone is offensive to me--imagine how it sounds to one of my colleagues who hasn't even read the rule yet.

You're more likely to be heard by being respectful.
